Compassberg (Afrikaans: Kompasberg), is a mountain peak of the Sneeuberge range in South Africa.

It is located 55 km due north of Graaff-Reinet in the Eastern Cape Province.

At 2502 metres, it is the highest peak in South Africa outside the Stormberg-Drakensberg massif.

It was named by Colonel Robert Jacob Gordon when he accompanied Governor Joachim van Plettenberg on a journey to the eastern frontier of the Cape Colony in 1778.

[citation needed] The mountain is composed of sediments of the Beaufort Series in the Karoo System, and extensively intruded by dolerite dikes and sills.
